Regular season totals, playoffs not included

Revised as of 7/23/2012

This page lists an estimate of how many points, compared to league average,
each team receives from the five elements of special teams: field goals/extra
points, kickoffs, kick returns, punts, punt returns. The total is then
converted into a DVOA percentage so that it can be added in to offense and
defense to create total team DVOA.

Field goal rating compares each field goal to the
league-average percentage of field goals from that distance. Yards of
field position from the other four elements of special teams are translated into points using a method that gives
each yard line a point value based on the average next score an NFL offense is
worth from that point on the field. Kickoffs and punts are based on
net yardage. Kickoff returns and punt returns are judged on return yardage only.
These numbers are then adjusted for weather and altitude based on stadium type
(cold, warm, dome, Denver) and week. The system is explained here.
Two-point conversions and onside kicks are not included.

LAST YEAR represents last year's rank. The top number in each category is in bold type.

The final five columns represent elements not found in the standard special
teams ratings.

HIDDEN represents the advantage teams have received from elements of
special teams generally out of their control: opposing field goals, kickoff
distance, and punt distance. It is listed as points worth of estimated field
position, and is ranked from the team with the biggest advantage to the team
with the biggest disadvantage.

WEATHER represents the estimated effect of weather, altitude, and domes on
each team's special teams performance. It is listed as points worth of
estimated field position, and is ranked from the team with the biggest
advantage to the team with the biggest disadvantage.

NON-ADJ VOA shows special teams DVOA without the adjustments for weather
and altitude.
